HC-12 SI4438/4463 wireless module Long distance 433M wireless serial port module UART

PS: HC-12 cannot communicate with HC-11. They work independently and use them in pairs.

1: The supply voltage is 3.2V~5.5V. (If the module is to be in the transmitting state for a long time, it is recommended to connect a 1N4007 diode in series when the power supply voltage exceeds 4.5V to avoid the built-in LDO heating of the module)

2: The default communication distance (open test): about 600m (the communication distance can be adjusted up to 1000m, the air baud rate is 5000bps).

3: Default idle current: 16MA (module operating current is different in different operating modes).

4: Module size: 27.8 mm × 14.4 mm × 4 mm.

5: Operating frequency range (433.4-473.0MHz, up to 100 communication channels) Maximum 100mW transmit power (settable)

6: The module supports software upgrade. (We provide upgrade software for our customers)

7: Default factory setting: working mode FU3, baud rate 9600bps, communication channel CH001 (433.4M).
